Description

Technical Field

[0001] The utility model relates to the technical field of single crystal furnaces, and more specifically, to a single crystal furnace tungsten wire rope with a protective structure. Background Art

[0002] In the production of single crystal silicon, a single crystal furnace is required to melt silicon material, and then a single crystal furnace pulling assembly is used to pull the molten silicon material to form a single crystal silicon rod. Specifically, the single crystal furnace pulling assembly includes a tungsten wire rope and a seed crystal connected to the end of the tungsten wire rope. The single crystal silicon rod is obtained by immersing the seed crystal in the molten silicon material and pulling it. In this way, the end of the tungsten wire rope is often at high temperature due to the connection with the seed crystal. Its aging speed is affected by the high temperature and ages faster. After a certain period of use, the tensile strength value decreases and it is easy to break, leading to accidents. In order to ensure the safe operation of the single crystal furnace, the operator will regularly replace the tungsten wire rope. The cost of replacing the tungsten wire rope is high, and the safety of production cannot be guaranteed.

[0003] The utility model patent with patent application publication number CN202123368504.3 discloses a tungsten wire rope protection structure, including a first protective cover and a second protective cover, the first protective cover is arranged on the tungsten wire rope, and the second protective cover is arranged outside the first protective cover; at least two slits are opened on the first protective cover along its axial direction, and the first protective cover can be split into at least two parts along the slit.

[0004] However, in actual use, the tungsten wire rope is prone to loose strands during long-term use. For example, the tungsten wire rope is composed of multiple thin tungsten wire ropes twisted together. When external force squeezes the ropes during use, the ropes will become loose. Therefore, it is necessary to provide a single crystal furnace tungsten wire rope with a protective structure. Utility Model Content
